I bought my set at Home Depot. I needed it to replace the stripped plastic gear in a meat slicer. What lame brain thought it was a good idea to put tamper resistant screws on a machine that would almost certainly need repaired? Oh wait,.they want you to throw it away and buy a new one. Nope, not happening. I'll keep my eyes open for a used commercial slicer that is built to last for decades of constant use.
